Heated Electromagnetic Stirrer

The heating electromagnetic stirrer uses electromagnetic induction to rotate the magnetic stir bar inside the container, generating eddy currents to heat the liquid. It is used in laboratories for mixing solutions and simultaneous heating, commonly employed in scenarios requiring temperature-controlled stirring, such as chemical reactions and sample pretreatment.
Selection
When selecting, consider the matching of the heating temperature range and stirring capacity with experimental requirements, pay attention to the corrosion resistance of materials, ensure temperature control precision based on experimental sensitivity, and ensure that the stirring speed covers both low and high-viscosity liquids. Safety features should include overheating protection and a non-slip base design.

Selection of Coating Thickness Gauges Using Magnetic and Eddy Current Methods on Different Substrates
This article introduces two main methods for coating thickness gauges: the magnetic method and the eddy current method. When choosing a method, the key is to determine it based on the electromagnetic properties of the substrate.
Application of Coating Thickness Gauges in Electroplating Thickness Detection
Coating thickness gauges are used to measure the thickness of electroplated layers, primarily employing the electromagnetic induction method for measuring non-magnetic coatings on magnetic substrates, or the eddy current method for measuring insulating coatings on non-magnetic metal substrates.
Eddy current thickness gauge measures metal coatings on non-conductive substrates.
The eddy current thickness gauge utilizes the principle of electromagnetic induction, generating an alternating magnetic field through the probe coil to induce eddy currents in the metal coating, thereby measuring thickness based on changes in coil impedance.
Laboratory Application Scenarios of Milligram Precision Balances
The milligram precision balance can accurately weigh up to 0.001 grams, primarily utilizing electromagnetic force compensation technology, and its performance is related to parameters such as repeatability and linearity error.
Eddy current thickness gauge detects coatings on non-ferrous metals.
The eddy current thickness gauge operates on the principle of electromagnetic induction, generating an alternating magnetic field through the probe coil, which induces eddy currents on the surface of non-ferrous metal substrates.
The principle of measuring dry film thickness with a coating thickness gauge
Coating thickness gauges measure dry film thickness through non-destructive methods, with commonly used principles including electromagnetic induction, eddy current, and ultrasonic methods.
For electromagnetic vibration tables, whether to choose sweep frequency or fixed frequency testing standards for simulating transportation is crucial; do not make a random selection if you are unsure.
The electromagnetic vibration table is used to simulate transportation vibrations and test the durability of products and packaging. There are two types of tests: fixed-frequency and sweep-frequency. The selection should be based on the test objectives and relevant standards to avoid arbitrary choices. For new products, it is recommended to first conduct a sweep-frequency test to identify resonance points, followed by fixed-frequency tests as needed.
